Alicia Kemp, 25, was over the legal limit when she hit Thanh Phan while riding through Perth’s city centre on 31 May.
The 51-year-old died in hospital days later after suffering a brain bleed.
His death thrust the issue of e-scooter regulations into Australia‘s national spotlight, prompting the city and several other local councils to suspend e-scooter hire services indefinitely.
Kemp, from Worcestershire, appeared at Perth Magistrates’ Court court via video link from prison on Monday.
She admitted a charge of dangerous driving causing death under the influence of alcohol.
Kemp will remain in custody until she appears at Perth District Court on 31 October, when a date will be set for her sentencing.
The charge of dangerous driving causing death carries a maximum penalty of 20 years in prison.
Under Western Australian law, e-scooter riders must wear a helmet, be sober, carry no passengers and be over 16.
